HAY-STACKER.

SPECIFICATION forming part of Letters Patent ITO. 408,429, dated August G, 1889.

Application filed April 9. 1889. Serial No. 306,577. (No model.)

To all, wlw/n, 1lb may concer/b:

Be it known that l, ARTHUR Elriavoon PLATT, of Ottumwa, inthe county of rapelle and State of Iowa, have invented a new and use ful Improven'ientin llay-Staekers, of: wh ich the following is a specification.

The invention consists in a new and improved hay-stacker, which will be hereinafter fully described and claimed..

Referring to the accompanying drawings, Figure l is a perspective View of my new and improved hay-stacker. Fig. 2 is a side eleva tion. Fig. 3 is a sectional. ldetail view showing the fork, the 'front end of the beam, and the catch for the said end. Fig. 4.- isa dettati" View showing the catch for locking the beam in its upright posit-ion. Fig. 5 shows in detail the springs ot the beam-axle, and vFig. f3 is a detail viewoii' the cat-ch 'tor the front end ol the beam.

The same let-ters of reference indicate corresponding parts in all the figures.

Referring to t-ho several partsiby let-ter, A indicates thc horizontal. frame of the stacker, on the ends of the cross-beams A A ottl which the supporti11g-wheels l are mounted.

(l C indicate parallel upright frames on the main frame, and C a cross-bar at' the lront ot t-he same.

D indicates t-he swinging beam which carries the fork. This beamhas thc axle D2, the rounded ends of which turn in bearings in the top of the frames C U. The front end or part D of the beam 'is reduced in thickness and curved at D, as shown. ()n this reduced parti of the beam is mounted the fork ld, having the curved main forward teeth E and `the rear upright teeth l?. lVhen theforlc is traue-,r back, the rear end of its f rame E beai's against the shoulders d of the beam, and a springcatch d. holds the fork in that position, the arch .Di assisting :in keeping the 'fork 'from running down on the lowered beam by its own weight.

The operating-rope 11 is fastened at oneeud to an eye f in the frame E", passes forward and up over a pulley Dt, journaled in the front end of the beam, then back hrough a guide d3 on the beam, back between flaring guidepins il* at the rear end of the beam, down around the end of the beam, which is formed with the guide-groove d", and through pulleys fl to the `fronti of the frame, as shown.

ln the recessed front end of'the frame A is pivoted an L-shaped catch G, the long end of which by its weight holds the catch end normally in a vertical position. An unlockingplate Il slides in a bearing on the beveled front end of the frame, its play being regulated by stops 71 h', the u1u-ight part of the catch (i fitting in the recessed frontend of this plate, while the rear end of the plate is bent up at right angles.

rlhe weight ot the fork normally holds the lront end of the beam down, with the point of catch. (i engaged in a notch 177 in that end of the beam.

In operation, the fork being held back by spring-catch rl', to raise a shock orload ofhay or loose straw, the operatiiig-rope l is drawn forward, thereby drawing the fork forward free ot the'spring-catch, down along t'hebeam l), so that its curved lingers lil will pierce and carry the hay. .I ust before the fork linishcs its forward movement the lower crossbar e of its head strikes the rear end of sliding plate ll, and, pushing it forward, turns catch (i so as to free it from the notched end ot' the beam. 'l'he pull of rope F then swings thebeam l) up,earrying with it the loaded fork, which is held forward on the beam, as it is raised, by a shoulder Il on the lower side of the same. When the hay is discharged from the lork as it is raised np' and back to its farthermost point', the hayslippingoft the points o'l' the si raight teeth l" will tilt the fork clear of the shoulder (I9 of the beam, so that it will slip down the beam until it bears against the shoulders d and is caught and held by the spring-catch (1. 'lhe weight of a large fork will of itself insure its slipping back into position, readyv for the beam to be again lowered. The rope F being then slaekeued the beam will swing down again into its original position, when the notched frontend ot' the beam striking the rounded upper edge of the pivoted catch G will swing the upper part of catch out and cause it to engage with the notched end of the beam, ready to repeat the operations above described.

To the inner sideot the upper part of one ot the frames are secured two springs I l',

IOO

the tree upper ends` ot which -are connected by ropes .l J with an eye l2 on that end of the beam-ade. These springs operate as cheek-springs to reduee and prevent the jar at the end ol the upward and downward swingr or movements, respeeiively, of the beam, as will be readily understood.

()n each side ol' the fronti end of frame A are staples K, to whieh lines are attached in moving:I` ihe stacker t'rom one plaee to another; also, stakes are driven through these staples into the ground to hold the staeker firm while in operation.

0n the cross-bar t" is mounted a eateh L, the head oi' which can be eaue'ht in a flat staple L at the side ot the beam end, and will serve to hold the oeam ereet while elearing up hay or doing airyv kind of work under the fork. This eateh has aA rope l. secured to its end, by pullingwhieh the eateh is treed from the beam, and this rope ean be tied around the bar t." to hold the eateh out oll the way.

From the foregoing;Y description, taken in eonneetion with the aeeompanying drawings, the eonstruetion, operation, and advantages ol` my invention will he readily understood. lt will be seen that my new and improved haystaeker is st rong' and comparativelysiniple in eonstruetion and exeeedingl)v efficient in its operation, being to a great extent automatic in loading and unloading7 itself'. Itis adapted partieularlv to stacking` ha)v that is in sl1oCl\'s,as ity will raise a shock at a time; also, it, is thoroughlyY adapted for takin;r straw away from a thrashiiig-machine and for staehY` ing' loose hay and hay in shocks.

llaving'thusdeseribed my invent ion, whatl elaim, and desire to seein-e byLeiters lateni, is-

l. ln a hay-siaeker, the eombination, with the horizont-al and upright trames, ot" the beam having,lr the axle and the redueed eurved forward part,the t'ork t'ormed with theshankt'rame E5 and havingl the eut-ved and straight teeth, and the operaiing-rope, substantially as setv t'orih.

L. in a ha,\'-stail er. the eombination, with i i y ine horizontal and upright frames, of the beam having the axle, the spring', andthe reduced forward part formed with the shoulders and having the pulley in its forward end, the fork havingthe curved and straight"J teeth, and the operating-rope, substantially as set forth.

3. In a hay-stacker, the combination, with the horizontal frame having,r the pulleys and the upright frames, of the beam havingr the axle, thel reduced forward part', and the shoulders, and havingr the pulley in its forward end, and the recessed rear end, the spring and gnid es, the fork havin g the curved an (isti-aight teeth, and the onerating-rope, substantially as set lorth.

l. ln a haystaeker, the combination, with the horizontal and upright frames, of the beam having tlie axle, Jche spring, andthe redin-ed im'ward part having the shoulders, the notched front end, and the pulley in its front end, the pivoted catch and Jche sliding plate, the l'orh having theeurved and stiraightteeth, and the operating-cord, substantially as set, forth.

5. In a hay-staeker, the Combination, with the horizontal and upright; frames, of the swing-ingr beam having' the axle and carrying the lork, and the check-springs I and I', secured at. their lower ends to the upright trames and connected at their upper ends to the beam-axle by the ropes J and J', substantially as set; forth.

t. In a hay-stacker, the combination, with the swinging' beam having the llat'J staple on the side of its rear end, of the L-shaped eateh adapted to engage with the same when the beam is elevated, and the rope L2, substautiiyly as set` forth.

7. In a hay-staeker, the combination of the horizontal frame having` the staples atits forward end, the upright frames, and the swing;- ing' beam, the torh, and the operating-rope, substantially as set forth.
